Abstract:
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>The size and persistence of the bubbles is one of the characteristics pursued by consumers of sparkling wine. The perlage is closely linked to nitrogen products, usually proteins of low molecular weight. Furthermore, bentonite and polyvinylpolypyrrolidone (PVPP) are glues used both in cleaning up the base wine and the sparkling wines, in other words, the fermentation in bottles, and can even drag from the liquid the phenolic compounds. The aim of this study was to evaluate the action of these two clarifiers upon the perlage, a syno

A estrutura tridimensional hidrofílica dos hidrogéis permite que estes mantenham a umidade ideal no leito das feridas, absorvam o exsudato e não causem danos ao novo tecido durante as trocas dos curativos. No caso dos hidrogéis, essas trocas podem ser menos frequentes. Além disso, curativos que auxiliem na remoção de tecidos necrosados e ainda sejam capazes de oferecer tratamentos extras que acelerem o processo de cicatrização são desejáveis. Este trabalho apresen

Solid polymer-drug dispersions are used to prepare and stabilize amorphous forms of poorly soluble drugs as a means of improving drug solubility, dissolution and bioavailability. Despite many reports on this subject, solid dispersion dissolution mechanisms have not been well understood. An early study was reported by Simonelli, Mehta and Higuchi (SMH) in 1969 and has served as a model for dispersion dissolution behavior. These authors proposed a dissolution model (SMH) which gave good agreement between their experimental results and model predictions for one drug and one type of PVP. Few resea

Abstract:
Sub-Saharan Africa is the region in the world that suffers the most from poverty and its worst effects: hunger, lack of water and diseases. And the problem is not even decreasing: in the past years there has been a peak in undernourishment in the continent. Furthermore, according to ongoing research, the area is expected to be one of the most affected by climate change. A solution that tackles at the same time water scarcity, diseases, hunger and greenhouse gas emissions is urgent. Luckily, with the development in the past years of the solar photovoltaic and battery technologies, these solutio

Abstract:
Bioavailability and clinical effectiveness of a poorly soluble drug can be highly affected by its formulation design. In this respect, research on solid dispersion of hydrophilic carrier has commenced a decade ago to resolve the problem of poorly soluble drug. However, the availability of solid dispersion is commercially limited due to the concerns of its physical instability, unpredictability and inconsistency formulation performance. This is attributed to the lack of fundamental understanding on the processing method, physicochemical properties of the obtained solid dispersion. Therefore, be

Abstract:
In this thesis, the author proposed and developed nanostructured materials based Surface Acoustic Wave (SAW) and conductometric transducers for gas sensing applications. The device fabrication, nanostructured materials synthesis and characterization, as well as their gas sensing performance have been undertaken. The investigated structures are based on two structures: lithium niobate (LiNbO3) and lithium tantalate (LiTaO3). These two substrates were chosen for their high electromechanical coupling coefficient. The conductometric structure is based on langasite (LGS) substrate. LGS was selected

In this study, the electrical characteristics of pentacene-based thin film transistors with PVP or PVP-PMMA as gate dielectric were discussed. PVP is usually used as gate dielectric due to its low leakage current and high mobility. However, device with PVP gate dielectric exhibits obvious the bias stress effect and hysteresis to ca

Besides, we analyze the stability of monolayer through the application of thermodynamics. Furthermore, we use the Vollhardt kinetics equation to simul

Due to the NP-hard complexity of HVRP and PVRP, most existing methods for solving HVRP and PVRP are heuristics or metaheuristics. The major contribution of this research is that we have developed a new metaheuristic approach, i.e. the Generic Intensification and Diversification Search (GIDS), for solving HVRP and PVRP.
